A successful awareness campaign ran with a 30-second video ad. You now want to remarket to audiences who saw it with memorable, shorter video ads. You should use bumper ads to make this happen.

• You should use non-skippable in-stream ads.
• You should use in-feed video ads.
• You should use masthead ads.
• You should use bumper ads.

The correct answer is: You should use bumper ads.

Explanation: If you want to remarket to audiences who saw your 30-second video ad, you should use bumper ads. Bumper ads are six-second, non-skippable in-stream ads that drive reach, frequency, and brand awareness. They are the building blocks of any successful YouTube ad campaign, complementing TrueView in-stream and Google Preferred while also making an impact as a standalone video solution. With high completion rates and industry-leading viewability and audibility rates, bumper ads are an efficient way to maximize your impact with audiences. They are also bought on a target cost-per-thousand impressions (CPM) through Google Ads, Display & Video 360, or Google Preferred.
